Digital signal output HD-SDI (SMTPE 292M), SD-SDI (SMPTE 259M), DV (IEEE 1394), and DVI (WUXGA, 1080p or SXGA) can be selected.
White balance adjustment White balance adjustment is possible using the white balance button on the front panel.
Standard color chart output The “Color bar” or the “50% white” screen can be displayed.
The following color tone adjustments are possible using the color tone level adjustment button and color tone selector button on the keyboard.
Color tone adjustment
• Red adjustment: ±8 steps • Blue adjustment: ±8 steps • Chroma adjustment: ±8 steps
Automatic gain control (AGC) The image can be electronically amplified when the light is inadequate due to the distal end of the endoscope being too far from the object.
• N (Normal): Normal image • H (High): The dark areas are darker and the bright areas are brighter than in the normal image.
Contrast
• L (Low): The dark areas are brighter and bright areas are darker than in the normal image.
The auto iris modes can be selected using the “iris mode” switch on the front panel.
• Auto: The brightness is adjusted based on the brightest part of the central part and the average brightness of the periphery part.
Iris
• Peak: The brightness is adjusted based on the brightest part of the endoscopic image.
• Average: The brightness is adjusted based on the average brightness of the endoscopic image.
Observation
Fine patterns or edges in the endoscopic images can be enhanced electrically to increase the image sharpness.
Image enhancement setting Either the structural enhancement or edge enhancement can be selected according to the user setup.
• Structural enhancement: Enhancement of contrast of the fine patterns in the image. • Edge enhancement: Enhancement of edges of the endoscopic image.
Switching the enhancement modes The enhancement level can be selected from 3 levels (OFF, 1, 2, and 3) using the image enhancement mode button on the front panel.
Image size selection The size of the endoscopic image can be changed using the “IMAGE SIZE” key on the keyboard.
Freeze An endoscopic image is frozen using an endoscope or the “FREEZE” key on the keyboard.
Switching the method of freezing the endoscopic image Pre-freezing: The image with the least blur is selected from the images captured in the set time period before freeze operation and displayed.
Fog free function When a compatible endoscope is connected to the video system center, the fog free function can be used.
Endoscope’s remote switches function The functions of the remote switches on the endoscope can be set in the user settings.
The following settings can be reset to their defaults using the reset button on the front panel.
